How will these calls be paid? Do I have to pay for the Internet while roaming? Of course, it will be cheaper than a regular call, but still expensive.
Have you ever been in "most countries"? Everywhere you go in Europe you will pay for the high quality internet. It's not free. Even you can use the WiFi connection in the airport but it will be cut a lot. Where you will take WiFI while you driving highway? And the idea about WiFi Satellites is very new. Elon Musk just start to move this idea but it will take a lot of time to make this idea 100% working, at least because Internet makes people totaly free and governments will do everything to set aside such perspectives.
